Ecu flash Vs Remap
Discussion
Hi.
Quick question. What’s the benefit of an ecu flash over a rolling road remap.
I understand that the remap will be tailored for my particular car but in the real world what will be the difference to me?
I’m not to fussed about eeking every last horsepower out of it. Reliability would be my bigger concern.

Technically both the same, with the RR remap having the benefit of fine tuning for your particular cars' outputs etc.Quick question. What’s the benefit of an ecu flash over a rolling road remap.

With the RR Remap, you'd expect the Tuner to pop your car on the RR to get a baseline & then tailor the tune to your car. That said, it would still be applied in the majority of cases via an ECU reflash. Depending on the car, this could be ECU out & flashed on the bench, or ECU accessed via the OBD port.
What you want to avoid is a generic remap/flash, or worst still a piggy back tune that basically tricks your cars ECU into behaving differently. These 2 options are of course the lower costs however.
Really does depend on the make/model of car & what you're trying to achieve? If just a few extra BHP out of a fairly basic motor then a generic remap/flash should be fine & low cost, but if a higher quality motor, I'd want the tuner to firstly have experience of that particular Marque & secondly be using either well known code or their own.
It’s for an S5 (v6t). It’ll be increased from 333 to 400 Bhp.
The same company offers both options. The reflash for £100 and the remap for £300. They have an all wheel drive rolling road.
They’re based in Barnsley. Not sure how reputable they are but seem to have good reviews.

Thanks & at that value I'd honestly steer well clear as that's very very cheap & as such the files will likely be generic &/or worst still (borrowed) from somewhere.The same company offers both options. The reflash for £100 and the remap for £300. They have a Lyn all wheel drive rolling road.

Extra cost (i'd assume) will be labour &/or use of the RR 2 or 3 times, but i'd be 'fairly' sure the files would be identical with purely some minor adjustment available on the latter.
A 20% bhp uplift on an Audi Turbo car, shouldn't stretch it too far, but it's a fair hike in power, so again for such a low cost & IMHO i'd avoid like the plague.
Try someone who works extensively on VAG cars for more realistic options & considerably better quality products/solutions.
Not sure where you're based, but if North West, i would be heading to Awesome GTI near Warrington.
Considering darkside developments charge about 600 odd quid for a rolling road custom remap and admit they barely make money on the remap alone (the margin is in the parts like exhausts, intercoolers, remedial work for the remap etc) I’d say a 100 quid remap is best avoided. If it was a 2 grand golf tdi fine but not something decent like an S5

I don't see the issue with a decent generic base map on standard cars. Cars leave factory with the same maps. Whats the issue if a tuner has spent many hours refining a map vs a few hours rushed on the rollers. Bit like an oem+ map
modified and race cars are different.
There’s no real issue with refined base maps (Revo etc) but if it’s a 100 quid special who knows what’s been done. Places with rolling roads normally apply a known safe base tune then work from there, they don’t normally work “live” from nothing .modified and race cars are different.
I would be a bit wary on a dearer car, if that screws up you cant just bail on it like something cheaper and cut your losses.
I think most tuners tend to, even when using a rolling road use it more for checking things are in spec and spotting issues rather than adjusting the map by that much as it takes a lot of development to come up with one in the first place, but they do seem to have some scope to adjust it.
Whereas a bloke with a laptop on the drive will plug in, upload a map, check it still starts then take your money and leave, most likely be fine but when mine went in to a tuners, they realised it wasn't making the expected airflow grams/sec and spent about five hours sorting it, turned out to be a faulty map sensor, they replaced it and it made the right numbers on their data logging. That can always happen, in that case it didn't make the expected power, in some cases it will just wreck your engine if some sensor is out, or they put the wrong map on or similar.
Though I do think, that a generic map from a respected tuner, on a healthy engine is fine, after all every car comes with the same OEM map for the make and model, though needs to be someone who knows them. Would avoid the Facebook advertised ones who do any car.

Thanks for all the replies.
I think to be safe I'll likely take it to a known good tuner. DMS in Birmingham have been recommended although AwesomeGTI are also close enough.
I guess my thinking with Awesome GTI (a considered reputable tuner) and Revo (who have an agent in Sheffield) is that they're just going to load a flash on like the place in Barnsley (Carlton Tuning) will, with a before and after dyno run in the case of AwesomeGTI (The Revo agent don't have a Rolling Road)
What made me start to think about this opting is watching Smacrac on you tube flash his S4 in his barn. If it's that easy why would i pay £600+?

Don't go to the place in Barnsley, I think I know who you mean and I don't think anyone here has a decent enough reputation.
Do yourself a favour and use Rick @ Unicorn Motor Developments over in Stockport. He's mapped 2 of my vehicles now, and one family member and both have been fantastic maps. I've never seen a bad word said.

A lot of these £100-1500-200 remap companies literally buy there whole remapping suite off ebay, the files are generic and not tested at all.
I purchased a 2005 MK1 Leon FR+ (1.9 PD150) a couple of years ago as a daily driver, I had been in the SEAT tuning world for around 11 years and had many remaps done in that time, the car went well but smoked like hell, so one day I took the file off using MPPS and had a look at it. max boost for the OEM turbo was 1.7bar file was requesting 2.0bar the whole rev range. There were other issues with the file as well.
The old owner told me who did the map, one of these man with a van styles that has built up enough custom to get a unit, So I messaged them and asked them about it, told them my findings etc, they initially said nah we havent done that car, I then sent them a screen shot of the exact car in one of their Instagram posts eventually they blocked me.
I took it to another PD diesel specialist, they put the stock file back on did some tests and then built it up from there, in the end the car pulled a lot harder for longer and smoked a lot less.
I've used Awesome GTI, REVO, APR during my time. MRC are very good, Unicorn Developments. Racingline OEM+ (formerly Volkswagen Racing)
